Description

Technical Field

[0001] This utility model relates to the field of pump body processing technology, and in particular to a clamping device for pump body processing. Background Technology

[0002] The "pump body" refers to the outer casing of a pump, which is typically used to house and support the pump's internal components, including the impeller, shaft, and seals. The design and material selection of the pump body play a crucial role in the pump's performance and service life. Different types of pumps (such as centrifugal pumps and plunger pumps) will have pump bodies with different shapes and structures.

[0003] To facilitate the processing and production of pump bodies, a clamping device is needed for the processing operations. For example, Chinese Patent Publication No. CN215510059U discloses a pump body shell processing clamping device. The moving device includes a first motor, a first serrated plate, a second serrated plate, a first gear, and a placement box. The first gear is mounted on a first gear and placed between the first and second serrated plates. This utility model discloses a pump body shell processing clamping device. After the first gear rotates, it drives the first and second serrated plates to move. The first serrated plate, the second serrated plate, and the first gear play a role in deceleration and buffering, preventing damage to the pump body shell caused by excessive pressure on both sides due to excessive rotation speed of the first motor.

[0004] The clamping device for some pump body processing uses a pair of clamping devices to clamp and fix the pump body. However, in actual operation, considering that such clamping devices can only clamp pump bodies with fixed shapes, and because different pumps (such as centrifugal pumps, plunger pumps, etc.) have different shapes and structures, the clamping device is limited in its range of application and also affects the processing efficiency of the pump body, resulting in poor practicality. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, which can only clamp pump bodies of fixed shapes, resulting in poor practicality. Therefore, this invention proposes a clamping device for pump body processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a clamping device for pump body processing, including a base, a support frame fixedly mounted on the top of the base, a processing unit set on the top of the support frame via a driving component, a clamping assembly for clamping the pump body provided at the bottom of the support frame, and the driving component for driving the processing unit to move.

[0008] The clamping assembly includes a compatible clamp, which enables the clamping assembly to clamp the pump body.

[0009] Furthermore, the clamping assembly includes a fixed seat and a movable seat. The fixed seat and the movable seat are fixedly installed and slidably connected to both sides of the bottom of the support frame, respectively. A cylinder is fixedly installed on the side of the support frame, and the shaft end of the cylinder is fixedly connected to the top of the movable seat.

[0010] Furthermore, the bottom of the fixed seat and the movable seat are rotatably connected to a rotating shaft via a groove. One end of the rotating shaft is fixedly installed with the compatible clamp. The compatible clamp is rotatably connected to the groove and has a rectangular rubber plate and an arc-shaped rubber plate on its side. A motor is fixedly installed on the side of the movable seat, and the shaft end of the motor is fixedly connected to the other end of the rotating shaft.

[0011] Furthermore, both the fixed seat and the movable seat have mounting cavities on their sides. A sleeve and a connecting rod are rotatably connected in each of the pair of mounting cavities. A driven bevel gear is fixedly installed at one end of the sleeve and the connecting rod, and the sleeve and the other end of the connecting rod are slidably connected.

[0012] Furthermore, one end of each pair of rotating shafts near the compatible clamp extends into the mounting cavity and is fixedly mounted with a driving bevel gear, which meshes and rotates with the driven bevel gear.

[0013] Furthermore, a limiting groove and a limiting post are respectively provided between one end of the sleeve and one end of the connecting rod, and the limiting groove and the limiting post are slidably connected.

[0014] The present invention provides a clamping device for pump body processing, which has the following advantages: the present invention can clamp the pump body through the clamping components, and can switch between compatible clamps by means of a motor and a pair of bevel gears. By switching the rubber plates of different clamps, it can clamp pump bodies of two shapes, such as rectangular or arc-shaped, thereby improving the applicability of the clamping. On the one hand, this makes the application range of the present invention wider, and on the other hand, it can effectively improve the processing efficiency of pump bodies. The structure is simple, the operation is convenient, and the practicality is strong. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A clamping device for pump body processing includes a base 1, a support frame 2 fixedly mounted on the top of the base 1, a processing unit 4 provided on the top of the support frame 2 via a driving component 3, and a clamping assembly 5 for clamping the pump body provided at the bottom of the support frame 2. The driving component 3 is used to drive the processing unit 4 to move.

[0023] The clamping assembly 5 includes a compatible clamp 6, which enables the clamping assembly 5 to clamp the pump body.

[0024] Considering that different types of pumps, such as centrifugal pumps and plunger pumps, have different shapes and structures in actual operation, the compatible clamp 6 is needed to hold the pump body in order to accommodate two shapes, such as rectangular or arc-shaped pump bodies.

[0025] In addition, the driving component 3 includes a hydraulic cylinder. The hydraulic cylinder is fixedly installed on the top of the support frame 2 by a fixing plate, and a sliding groove is passed through its top. The processing unit 4 is slidably connected in the sliding groove by a support plate. The support plate is fixedly connected to the shaft end of the hydraulic cylinder.

[0026] Furthermore, the processing unit 4 can specifically be a device for drilling, welding, and deburring.

[0027] Furthermore, the clamping assembly 5 includes a fixed seat 51 and a movable seat 52. The fixed seat 51 and the movable seat 52 are fixedly installed and slidably connected on both sides of the bottom of the support frame 2, respectively. A cylinder 53 is fixedly installed on the side of the support frame 2, and the shaft end of the cylinder 53 is fixedly connected to the top of the movable seat 52.

[0028] Furthermore, the bottom of the fixed base 51 and the movable base 52 are rotatably connected to a rotating shaft 55 via a groove 54. One end of the rotating shaft 55 is fixedly mounted with the compatible clamp 6. The compatible clamp 6 is rotatably connected to the groove 54 and has a rectangular rubber plate and an arc-shaped rubber plate on its side. A motor 56 is fixedly mounted on the side of the movable base 52, and the shaft end of the motor 56 is fixedly connected to the other end of the rotating shaft 55.

[0029] It is worth mentioning that if the current rectangular rubber plate cannot clamp the pump body, the motor 56 drives the rotating shaft 55 to drive the compatible clamp 6 to rotate, and then clamps the pump body by replacing the arc-shaped rubber plate.

[0030] More specifically, both the fixed seat 51 and the movable seat 52 have mounting cavities 57 on their sides. A sleeve 571 and a connecting rod 572 are rotatably connected in each of the pair of mounting cavities 57. A driven bevel gear 58 is fixedly installed at one end of the sleeve 571 and the connecting rod 572. The other end of the sleeve 571 and the connecting rod 572 are slidably connected.

[0031] In general, one end of each pair of rotating shafts 55 near the compatible clamp 6 extends into the mounting cavity 57 and is fixedly mounted with a driving bevel gear 59, which meshes and rotates with the driven bevel gear 58.

[0032] It should be added that the mounting cavity 57, the groove 54 and the motor 56 are on the same horizontal line, and the rotating shaft 55 is fixedly connected to the shaft end of the motor 56, so that the motor 56 drives the rotating shaft 55 to rotate. Because the rotating shaft 55 is fixedly connected to the compatible fixture 6, the rotating shaft 55 drives the compatible fixture 6 to rotate at the same time.

[0033] Specifically, while the motor 56 drives the rotating shaft 55 to rotate, the rotating shaft 55 also uses the active bevel gear 59 in conjunction with the driven bevel gear 58 to drive the connecting rod 572 to rotate. The connecting rod 572 then causes the sleeve 571 to rotate synchronously due to the limiting groove 573 and the limiting post 574.

[0034] Among them, the active bevel gear 59 and the driven bevel gear 58 on the other side are used to make a pair of compatible clamps 6 rotate synchronously, so as to replace the clamp rubber plate.

[0035] It is worth mentioning that the advantage of having the sleeve 571 and the connecting rod 572 is that the compatible clamps 6 on both sides can be switched simultaneously by the motor 56, and the sliding connection between the two prevents jamming when adjusting the position of the movable seat 52.

[0036] In addition, by using the limiting groove 573 and the limiting post 574, it can be ensured that the sleeve 571 and the connecting rod 572 can achieve synchronization when they rotate.

[0037] Finally, a limiting groove 573 and a limiting post 574 are respectively provided between one end of the sleeve 571 and the connecting rod 572, and the limiting groove 573 and the limiting post 574 are slidably connected.

[0038] Working method: During operation, cylinder 53 drives movable seat 52 to adjust its position in order to clamp the pump body;

[0039] Then, if the rectangular rubber plate cannot clamp the pump body, the motor 56 drives the rotating shaft 55 to rotate. At the same time, the rotating shaft 55 will also use the active bevel gear 59 and the driven bevel gear 58 to drive the connecting rod 572 to rotate. The connecting rod 572 will then cause the sleeve 571 to rotate synchronously due to the limiting groove 573 and the limiting post 574. Then, the active bevel gear 59 and the driven bevel gear 58 on the other side will cause a pair of compatible clamps 6 to rotate synchronously, so as to achieve the purpose of replacing the clamp rubber plate.

[0040] Finally, the hydraulic cylinder drives the machining unit 4 to process the pump body.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
